- Multiple, short stints at different companies. Sometimes things happen but if you have a track record of jumping from one place to another I am pretty confident you won't stay around very long if I hire you.

- Multiple pages. A long resume is not impressive. Typically it is just annoying because it makes it harder to find key information. It shows a lack of ability to communicate in a concise manner. I have worked for several companies, completed three degrees, have worked in multiple functions, lead a wide variety of teams, and am still able to keep my resume to a single page. If you need more than one page, fine, but if you need several you are doing something wrong. If there are multiple candidates for an opening your resume is going to the bottom of the pile.

- Keyword stuffing. This typically means the candidate is writing their resume for a search engine. They aren't really looking for the right job...just "a" job. It also shows a lack of ability to communicate effectively.

- "Creative Resumes". Don't be cute. Don't use alternate layouts, photos, background colors, interesting fonts, or graphics. It doesn't get you noticed. At least not in the way you want to get noticed. Stand out by being concise and organized. Show you that you can identify the most important aspects of your career and communicate them effectively.

- Buzz words. Be a human and communicate like a human.

- Lack of precision. Don't just say "Improved application speed" say "Improved application throughput by 50%". When you lack precision my conclusion is either a) You are hiding something or b) You don't know how to communicate effectively.

- Objective statements. These aren't a red flag. They are just a waste of space. Nobody looks at them. They clutter the resume and make it longer than it needs to be.
